Microchip | MIC26600YJL-TR

The MIC26600YJL TR is a constant frequency, synchronous buck regulator featuring a unique digitally modified adaptive ON-time control architecture. The MIC26600 operates over an input supply range of 4.5 V to 26 V and provides a regulated output at up to 7 A of output current. The device operates at a switching frequency of 300 kHz.

The MIC26600 offers a full suite of protection features to ensure protection of the IC during fault conditions. These include undervoltage lockout to ensure proper operation under power-sag conditions, internal soft-start to reduce inrush current, fold-back current limit, “hicc up” mode short-circuit protection and thermal shutdown.
